[poppler] Help with pdftohtml background image resolution

[ChunWei Ho]

I've been using pdftohtml (http://pdftohtml.sourceforge.net/) for PDF
to HTML conversion for my application, and recently tried to upgrade
it to use poppler-utils.

I usually invoke it as "pdftohtml -c -noframes [input pdf] [output html]"

The commandline interface and all is fine but the images (I understand
a background image is generated per page) is now really bad. I did a
check and under the old pdftohtml project, each background image (PNG)
for a page is 1785x2526 resolution.

Under poppler-utils, each background image (PNG) is 594x843 resolution.

Can someone point me in the right direction to change/fix this? There
doesn't appear to be a command line parameter for this.
The new background images are bad to the extent of unusable. Which is
a shame, because I really want to move to poppler-utils for the
unicode and continued support.

Chun
